carbon dioxide (CO2) is the gas mainly responsible for global warming (the greenhouse effect). the burning of fossil fuels is a major cause of the increased concentration of CO2 in the atmosphere. carbon dioxide is also the end product of metabolism. a general overall equation for this very complex process represents the degradation of glucose (c6H12O6) to carbon dioxide (CO2) and water (H2O)
using glucose as an example of food, calculate the annual human production of CO2 in grams assuming that each person consumes 5.05 X 10^2 g of glucose per day. the worlds population is 6.5 billion and there are 365 days in the year.
I have NO IDEA how to even start this? Help? please show how to work it.
C6H12O6 + 6O2 ==> 6CO2 + 6H2O
Here is an example of a stoichiometry problem. Using that example, solve for moles glucose and convert to grams. Then multiply by consumption by one human x number of humans.

To calculate the annual human production of CO2 in grams, we need to determine the amount of glucose consumed by each person per year and then convert it to the amount of CO2 produced.
First, let's calculate the amount of glucose consumed per year by each person:
Daily glucose consumption = 5.05 x 10^2 g
Yearly glucose consumption = daily consumption x number of days in a year
Yearly glucose consumption = (5.05 x 10^2 g) x 365 days
Next, let's calculate the total amount of glucose consumed by the world's population per year:
Total yearly glucose consumption = yearly glucose consumption per person x world population
Total yearly glucose consumption = (5.05 x 10^2 g) x 365 days x 6.5 x 10^9 people
Now, let's convert the total glucose consumption into the amount of CO2 produced:
Glucose degradation equation: C6H12O6 → 6CO2 + 6H2O
From the equation, we can see that every molecule of glucose produces 6 molecules of CO2.
To convert grams of glucose to grams of CO2, we need to multiply the total glucose consumption by the ratio of moles of CO2 to moles of glucose (6:1). The molar mass of glucose (C6H12O6) is approximately 180 g/mol, while the molar mass of CO2 is about 44 g/mol.
Finally, we can calculate the annual human production of CO2 in grams:
Annual CO2 production = ((total yearly glucose consumption) / (moles of glucose)) x (moles of CO2) x (molar mass of CO2)
Let's substitute the values into the equation:
Annual CO2 production = ((5.05 x 10^2 g) x 365 days x 6.5 x 10^9 people) / (180 g/mol)) x (6 moles of CO2) x (44 g/mol)
By simplifying the equation and calculating the result, you will get the annual human production of CO2 in grams.
